Bay State Heating & Air — multi-decade heating & cooling contractor serving Natick and the surrounding towns. Furnace and AC repair, full system installs, EV chargers, generators, mini-splits. Snap a photo of your unit's tag, get a real quote back within the hour.
Residential and light-commercial HVAC. Service calls, full system installs, retrofits, rebates. If it heats or cools your house, we work on it. If we don't, we'll tell you who does.
No heat. Short-cycling. Pilot won't stay lit. Strange noise from the basement at 3 AM. We get out same-week — same-day if it's an emergency in winter.
Central air, ductless mini-splits, heat-pump conversions. Whether the unit's leaking, the coil's frozen, or you want to ditch the window units this summer — we quote it straight.
Hydronic systems, baseboard, indirect tanks, tankless water heaters. We work on old steam systems most companies won't touch, and we install modern high-efficiency replacements.
Single-zone, multi-zone, full whole-house. The cleanest way to add AC and supplemental heat to a house without ductwork. Mitsubishi, Fujitsu, LG installs.
Level 2 home chargers — 240V circuits, panel upgrades if needed, permit pulled and inspected. Tesla, ChargePoint, JuiceBox, Wallbox — bring your own or we'll source it.
Generac, Kohler, Cummins standby generators. Concrete pad, gas line, transfer switch, the whole job. Sized for your house and tested under load before we leave.
We're based in Natick and service everything inside about a 20-minute radius — same-week routine, same-day emergency. If you're not on the list, call us anyway — we still might cover you.
We don't send a salesman in a polo shirt. The person who quotes the job is the person who does the work. Here's exactly what happens after you call or fill the form.
Call (508) 555-0173 or use the quote form — snap a photo of your unit's model tag if you can. Takes 90 seconds.
We text you back inside an hour with a real number — not a range, not a "starting at." If a visit is needed first, we'll say so.
Same-week service calls, 2–4 weeks for full installs. Emergencies get same-day, no overtime fees if it's during business hours.
One crew, start to finish. We don't leave until it's tested, cleaned up, and you've seen it work. Permits and inspections included.

We don't ask for reviews and we don't pay for them. Sixteen 5-star ratings on Google from neighbors who actually live within a few towns of us — the kind of word-of-mouth a contractor lives or dies by.
"Furnace died on the coldest Sunday of January. Got someone here in three hours, fixed for less than the quote. Cleaned up after. Will never call anyone else."
"Quoted three companies for a Mitsubishi mini-split install. Bay State was the lowest by $1,800, did the cleanest work, and pulled the rebate paperwork themselves. No comparison."
Trades guys answer phones. The fastest way to get a real number on what your repair or install will cost is a thirty-second phone call. Quote form's fine too — same-day reply, either way.
